Wind protection for apparatus for paying out an insulation support sheet

Abstract

A method for providing a roof structure of the type having a plurality of purlins spaced apart from one another in a parallel arrangement is disclosed. A first section of the roof structure, which includes purlins, a support sheet, insulation material, and hard roofing material, is completed. A carriage is then moved in a first direction along the length of the purlins and away from the first section of the roof structure to define a gap between the completed first section and the carriage. The movement of the carriage pays out a support sheet from the carriage so that the support sheet depends from adjacent purlins in the gap. A wind barrier, which is in a generally horizontal position to prevent wind from blowing vertically through the gap, is provided, thereby hindering wind disturbance of the support sheet.

We claim: 
     
       1. A method for providing a roof structure of the type having a plurality of purlins spaced apart from one another in a parallel arrangement comprising: a. completing a first section of the roof structure comprising purlins, a support sheet, insulation material, and hard roofing material;   b. moving a carriage in a first direction along the length of the purlins and away from the first section of the roof structure to define a gap between the completed first section and the carriage, where moving the carriage pays out a support sheet from the carriage so that the support sheet depends from adjacent purlins in the gap; and   c. positioning a wind barrier, attached to the carriage and extending in a second direction opposite the first direction towards the first section of the roof structure, in the gap to prevent wind from blowing vertically through the gap, and applying a layer of insulation material above said wind barrier thereby the wind barrier hindering wind disturbance of the support sheet and the insulation material.   
     
     
       2. The method of claim 1 including applying the insulation material above the support sheet, in the gap, where the wind barrier is sufficient to hinder wind disturbance of the insulation material. 
     
     
       3. The method of claim 2 in which the insulation material is laid laterally across the purlins, and in which the gap is substantially equal to the width of the insulation material. 
     
     
       4. The method of claim 2 in which the insulation material is dispensed from a roll which is mounted on the carriage, the insulation material being applied in a direction parallel to the purlins. 
     
     
       5. The method of claim 1 in which the wind barrier is positioned above the payed out support sheet. 
     
     
       6. The method of claim 1 in which the wind barrier is positioned underneath the payed out support sheet. 
     
     
       7. The method of claim 1 in which the wind barrier has rollers which roll along the top of the purlins. 
     
     
       8. The method of claim 1 in which the wind barrier is sufficient for fall protection. 
     
     
       9. The method of claim 1 in which the carriage has a plurality of carriage sections and support sheets, where the support sheets are payed out downwardly from dispensers mounted on the carriage sections and positioned substantially above the purlins to define a vertical space between the dispensers and the purlins, thereby forming vertical portions in the support sheets, the method further comprising: a. aligning the vertical portions of the support sheets from adjacent dispensers to prevent wind from blowing horizontally in a direction along the length of the purlins through the vertical space;   b. feeding the support sheets around turning bars positioned near the bottom of the vertical space to turn the support sheets in a generally horizontal direction; and   c. applying the insulation material above the horizontal portions of the support sheets, where the vertical portions of the support sheets are sufficient to hinder wind disturbance of the insulation material.   
     
     
       10. The method of claims 1, wherein the wind barrier is positioned above the plurality of purlins. 
     
     
       11. A method for providing a roof structure of the type having a plurality of purlins spaced apart from one another in a parallel arrangement comprising: a. completing a first section of the roof structure comprising purlins, a support sheet, insulation material, and hard roofing material;   b. moving a carriage in a first direction along the length of the purlins and away from the first section of the roof structure to define a gap between the completed first section and the carriage, where moving the carriage pays out a support sheet from the carriage so that the support sheet depends from adjacent purlins in the gap;   c. positioning a wind barrier, attached to the carriage and extending in a second direction opposite the first direction towards the first section of the roof structure, in the gap to prevent wind from blowing vertically through the gap, thereby hindering wind disturbance of the support sheet;   d. Positioning a first layer of insulation material above the wind barrier; and   e. applying the first layer of insulation material parallel to the purlins, above the support sheet, and in the gap, and applying a second layer of insulation material on top of the first layer of insulation material, where the wind barrier is sufficient to hinder wind disturbance of the insulation material.   
     
     
       12. The method of claim 11 comprising applying hard roofing material on top of the second layer of insulation material before the wind barrier is moved from the gap. 
     
     
       13. The method of claim 11 in which the second layer of insulation material is laid laterally across the purlins, and in which the gap is substantially equal to the width of the insulation material. 
     
     
       14. The method of claim 11 in which the wind barrier is sufficient for fall protection. 
     
     
       15. The method of claim 11, wherein the wind barrier is positioned above the plurality of purlins. 
     
     
       16. A method for providing a roof structure of the type having a plurality of purlins spaced apart from one another in a parallel arrangement comprising: a. providing a plurality of carriage sections mounted for movement in a first direction to pay out support sheets so that the support sheets depend from adjacent purlins and extend parallel to the length of the purlins, where the carriage sections include dispensers for paying out the support sheets, where the dispensers are positioned substantially above the purlins to define a vertical space between the dispensers and the purlins;   b. paying out the support sheets downwardly from the dispensers, thereby forming vertical portions in the support sheets; and   c. aligning the vertical portions of adjacent support sheets in a generally co-planar orientation to hinder the wind from blowing horizontally in a direction along the length of the purlins through the vertical space;   d. feeding the support sheets around turning bars positioned near the bottom of the vertical space to turn the support sheets in a generally horizontal direction so that the support sheets form horizontal portions; and   e. applying insulation material above the horizontal portions of the support sheets, where the vertical portions of the support sheets are sufficient to hinder wind disturbance of the insulation material.   
     
     
       17. The method of claim 16 in which adjacent turning bars on adjacent carriage sections are generally co-linear. 
     
     
       18. The method of claim 17 in which the turning bars are spaced apart from each other by a distance less than about 3 inches.
